By the late 1900’s Terrence Parker won a legal case against the Province of Ontario for the right to grow and use cannabis for the treatment of his epilepsy. After his landmark ruling the Government of Canada established the Canadian Medical Marijuana Access Regulations or MMAR that granted legal access to cannabis for Canadians for medical purposes. Under these new regulations, patients would need to get a prescription from their physician in order to grow and consume. Eventually by the 2013 Health Canada was assigned as the regulator for ensuring the quality and safe production and distribution of medical cannabis.
On June 19, 2018 the Cannabis Act was passed by the senate in the Federal Government making recreational cannabis legal on October 17, 2018. The rules and regulations governing recreational cannabis differ from Province to Province with respect to minimum age, consumption, advertising and distribution.
